When system switches on PSI function, a phase shedding
will be presented. Only one is active in the emulation mode
while other phases are shed. Figure 19 indicates a PSI-- on
transition from a 3-- phase mode to a single phase mode.
While staying stable in PSI mode, the PWM signal of phase
Auto--PSI Function:
In Auto-- PSI mode (APSI_EN=1, PSI=1), the device will
monitor VID lines for transition into/out-- of Low Power
States. Figures 21 and 22 describe the Auto-- PSI function
during VID transitions.
1 will vary from a low-- state level to high level while other
phases all go to mid-- state level (1.5 V typical). Vice verse,
when PSI signal goes high, the system will go back to the
original phase mode such as shown in Figure 20.
